Application filed February 14, 1927., serial No. 168,187.

This invention relates to a furnace-cleaning apparatus, and one object of the invention is to provide an apparatus of this character, the elements of which may be mountedupon a truck and thereby from one place to another.

Another object of the invention is to so arrange the elements of the cleaning a paeasily transported ratus upon a platform forming part 0 the truck that they will be entirely disposed within the confines of the platform and thereby eleminate danger of their being damaged by striking obstructions while the truck is being moved from one place to another.

Another object of the invention is to cause thejweight to be well distributed over the plalzlform and thereby provide a balanced loa Another object of the invention is to-prevent the elements of the cleaning apparatus from being damaged by vibration when the apparatus is in use. j

The improved furnace-cleaning apparatus is illustrated inthe accompanying drawings, wherein v Fi re 1 is a view showing the apparatus in si e elevation;

Fig. 2 is a top plan view of the same;

Fig. 3 is a sectionalview through the dust collectgir 'illustrating the manner of releasably connectin sections of the hose forming'a portion 0 the .apparatus. V

The furnace-cleaning apparatus constitutin the subject-matter of this invention inclu es a truck which is of a conventional construction and indicated in general by the numeral 1. This truck is provided with a 1 platform 2 which extends'rearwardly from the driverscab 3 and is formed with aflatuninterrupted upper surface. The. platform is rectangular in shape and preferably of greater length tgian width. While the vehicle constituting. the portable carrier has been illustrated asan automobile truck, it

will be understood that any vehicle including a platform corresponding to the platform 2. maybe employedby the numeral;. 4, a fan operating motor 5 which operates the fan through the medium of a belt 6, a dust collector 7, a removable dust receptacle or bag 8 and a hose 9 leading from the inlet of the suction fan 4. By referring to Fig. 1, it will be seen that the motor 5 is mounted upon the platform2 adjacent its forward end and at one side thereof-and the fan 4 is firmly secured upon the platform rearwardly of the 'motor 5 and preferably above the rear axle of the truck. The dust collector 7 is disposed adjacent the front of the platform at the opposite side thereof from the motor 5 and consists of a casing 10 which is circular in top plan and is partially closed at its upper end by an annular flange or head 11. The lower portion 12 of the casing tapers downwardly and terminates in a reduced outlet spout 13 adapted to be passed through an opening formed in theplatform2 and project below the platform" a sufficient distance to have the closure cap 14 applied thereto when the apparatus is not 1n use or the neck of the dust receptacle or sack 8 connected therewith. The sack 8 is formed of fabric and has its neck firmly secured about a metal ring 15 of such internal diameter that it may fit snugly upon the projecting lower end portion of the neck 13. Internal bayonet slots 16 are formed in the ring and spaced from each other circumferentially of the ring for reception of the pins 17 which project radially from the neck. It will thus be seen'that the receptacle ma be firmly 'engaged with the neck of the co ector but may be easily removed when the truck is to be moved or the receptacle becomes filled and needs to be emptied. In its upper portion the collector carries an annular air deflector 18 v which extends downwardly from the head 11 and is intended to im art. a whirling motion to dust laden air w ich enters the casing air-passes withoutcarrying the'dust with The pipe 19 extends diagonally across t e platform and terminatesin 'a. downwardly curved free end portion 20 disposed above the outletneck 21 of the fan 4 and connected with the outlet neck of the fan by a shortsection of flexible tubing 22, the ends ofwhich are securely butremovably fastened to the adjacent ends of the pipe and outlet neck. By having the tube 22 formed of flexible ma- 'terial, such as reinforced fabric or the like,

the collector will not-be affected by vibration suction fan; This fan is ofa .conventiona construction and includes the usual shaft 23 carrying a pulley 'wheel 24 about which passes the belt 6 which is engaged with the pulley wheel 25 carried by the shaft 26 ofthe motor 5. The pipe 9 or hose asitmay be called has voneend attached to the'inlet of the suction fan. This hose is of suflicient length'to reach from the truck to the furnace to be cleaned and is preferably formed of a number of sections 27 which may be of an desired length but are preferably six feet I. ong and twelve inches in diameter;

These sections are placed in end to end engagement with each other and have their ad'- Jacent ends releasably connected so that they may be taken apart or additional sections added if necessary".. As a preferred means forconnecting adjoining sections, I employ asplit s1eeve 28 of sufiicient length to overlap the adjacent ends of the sections and of suflicient diameter to fit snu Stra ly about them. 29 are passed about the .end portions of t e couplin will cause t e ing engagement with the .hose sections. The hose may be coiled and placed upon the platplatform,

.will be very well balanced and no parts will project from the sides or ends of the platfornn-as shown in Fig. 1, when not in use and add tional pipe-sections ma be piled upon the'platformrearwardly 'o the collector if so desired. By having the elements forming the cleaning apparatus. mounted upon the as shown inFigs. 1 and 2, the load Therefore, they will not be liable to to be struck when the truck is-in motion and tudinally upon the latform to collector and the ust bag'is removed and sleeve and when tightened eeve'to be held in tight binddamaged. When the deviceis in operation,

the hose is extended from the truck into the cellar in which is located the furnace to be cleaned and the inner end of the hose applied to various portions of the furnace or pipes from whichit is desired to remove soot. The suction of the fan draws the soot through the hose into the fan housing and expels it through the ipe 19 into the dust collector through whic it passes intothe bag 8. When the bag is filled, itcan be easily removed and a new one substituted while the filled one is being emptied.- After the furnace has been 4 cleaned, the hose is again coiledupon the platform and surplus sections placed lon t erear 0ft e may be placedin the cab'of the truck or 7 the side of the body near the top thereof,'a

suction device, a flexible tube connecting'the' I inlet pipe with the outlet of the suction device, radial pins on the reduced neck of the tapered body, a receptacle, and a ring in the top of said receptacle fitting closely around the neck and constructed to engage and be held by the pins thereon.

In testimony whereof I afiixm CHARLES E; WHIT si nature. L. s.']
